Abstract

It is a frequently observed phenomenon that curving of rail vehicles involves friction induced oscillations. In fact the presented study investigates vibrations with a frequency of 80 Hz occurring at a light railway vehicles in Stuttgart (Germany) in curves with a radius between 50 and 200 m. The aim of the investigation is to identify the oscillation and transmission mechanism and their dominate parameters applying a multi-body simulation in the time domain. The model consists of vehicle and track and considers the structural dynamics of the wheelset and the bogie frame to reach a validity range up to 250 Hz. The system is modelled using the commercial MBS software SIMPACK. The results turned out to be useful to minimize the vibrations at the real vehicles.
